Utilizing a mnemonic for communicating sensitive data

ABSTRACT

Systems and methods for utilizing a mnemonic to communicate sensitive data to an agent are disclosed. In aspects, a computer-implemented method comprises: establishing a telephone connection between a caller and an agent; entering an encryption key received from the agent into a mnemonic application of the computer device to permute an algorithm of the mnemonic application; receiving sensitive data in the form of one or more alphabetic, numeric or alpha-numeric sequence; initiating the mnemonic application to generate a mnemonic of the sensitive data using the encryption key, wherein the mnemonic is a sequence of words representing the sensitive data; displaying the mnemonic to the caller; and conveying audio communication of the mnemonic to the agent through the telephone connection to enable remote decoding of the mnemonic back into the at least one sensitive number sequence.

BACKGROUND

The present invention relates generally to securely communicating sensitive information and, more particularly, to utilizing a mnemonic for audio communication of sensitive information, such as credit card numbers.

Presently, the problem of securely transmitting credit card information or other sensitive numeric or alphabetic data over a computer network is being addressed in multiple ways, including the use of various encryption devices and methods. However, such methods are directed to network communications between computer devices, and do not address the real-world problem of communicating sensitive number sequences verbally over a telephone connection. For example, instances may arise when an agent speaking with a user (e.g., caller) needs the user to verbally communicate the user's credit card number, expiration data, and card verification value (CCV) code to the agent. However, it may be undesirable for the user to convey such sensitive information, such as when the user is in public. This is especially true in the case of a poor telephone connection, where the user may need to repeatedly verbally communicate the sensitive information to the agent over the telephone, putting the user's sensitive information at risk of theft.

SUMMARY

In an aspect of the invention, a computer-implemented method for utilizing a mnemonic to communicate sensitive data to an agent includes: establishing, by a computing device, a telephone connection between a caller and an agent; entering, by the computing device, an encryption key received from the agent into a mnemonic application of the computer device to permute an algorithm of the mnemonic application; receiving, by the computing device, sensitive data in the form of one or more alphabetic, numeric or alpha-numeric sequence; initiating, by the computing device, the mnemonic application to generate a mnemonic of the sensitive data using the encryption key, wherein the mnemonic is a sequence of words representing the sensitive data; displaying, by the computing device, the mnemonic to the caller; and conveying, by the computing device, audio communication of the mnemonic to the agent through the telephone connection to enable remote decoding of the mnemonic back into the at least one sensitive number sequence. Advantageously, the method enables secure telephone communication of sensitive data.

In aspects, the method step of entering the sensitive data into the mnemonic application of the computing device includes initiating, by the computing device, a camera to take a digital picture of the sensitive data; and initiating, by the computing device, a character recognition function to determine the sensitive data from the digital picture. Advantageously, this method step enables for quick and secure entry of sensitive data into the computing device.

In another aspect of the invention, there is a computer program product for utilizing a mnemonic to verbally communicate sensitive data. The computer program product comprises a computer readable storage medium having program instructions embodied therewith. The program instructions are executable by a computing device to cause the computing device to: enter an encryption key received from a remote agent into a mnemonic application of the computing device to permute an algorithm of the mnemonic application; enter sensitive data in the form of one or more alphabetic, numeric or alpha-numeric sequence into the mnemonic application of the computing device; initiate the mnemonic application to generate a mnemonic using the encryption key, wherein the mnemonic is a sequence of words representing the sensitive data; display the mnemonic to the caller; and convey audio communication of the mnemonic to the agent through the telephone connection to enable remote decoding of the mnemonic back into the at least one sensitive number sequence. Advantageously, the computer program product enables secure telephone communication of sensitive data.

In aspects the computer program product further includes program instructions executable by a computing device to cause the computing device to: initiate a camera to take a digital picture of the sensitive data; initiate a character recognition function to determine the sensitive data from the digital picture; and store the sensitive data in a database of the computing device. Advantageously, the program instructions enable quick and secure entry of sensitive data into the computing device.

In another aspect of the invention, there is a system for utilizing a mnemonic to verbally communicate sensitive data. The system includes: a CPU, a computer readable memory and a computer readable storage medium associated with a computing device; program instructions to enter an encryption key received from a remote agent into a mnemonic application of the computing device to permute an algorithm of the mnemonic application; program instructions to enter sensitive data into the mnemonic application of the computing device; program instructions to initiate the mnemonic application to generate a mnemonic using the encryption key, wherein the mnemonic is a sequence of words representing the sensitive data; program instructions to display the mnemonic to the caller; and program instructions to convey audio communication of the mnemonic to the agent through the telephone connection to enable remote decoding of the mnemonic back into the at least one sensitive number sequence; wherein the program instructions are stored on the computer readable storage medium for execution by the CPU via the computer readable memory. Advantageously, the system enables secure telephone communication of sensitive data.

In aspects, the system further includes: program instructions to initiate a camera to take a digital picture of the sensitive data; program instructions to initiate a character recognition function to determine the sensitive data from the digital picture; and program instructions to store the sensitive data in a database of the computing device.

DETAILED DESCRIPTION

The present invention relates generally to securely communicating sensitive information and, more particularly, to utilizing a mnemonic for audio communication of sensitive information, such as credit card numbers. In aspects, the present invention enables a user (e.g., a caller) to more easily and securely communicate a credit card number or other sensitive information verbally to an agent while in a public space. Upon establishing a telephone connection between an agent and a user, the agent and user agree on an encryption key (e.g. a two character key) that will be used to permute an algorithm of the mnemonic application. In aspects, the agent will provide the encryption key to the user (e.g., audio communication of encryption key over the telephone connection), and the user will enter the encryption key into the mnemonic application of their mobile device. With this method, the encryption key is not heard by anyone around the user, preventing anyone around the user from overhearing and interpreting a mnemonic later generated by the mnemonic application.

In embodiments, the invention uses an input device of the user's mobile device (e.g., smartphone) to enable the user to input sensitive data into the mnemonic application. In embodiments, the input device is in the form of a mobile device keyboard or a mobile device camera. By way of example, a mobile device camera may be utilized by the user to capture an image of a credit card number. The credit card number may then be stored in the mobile device for use in future transactions. The mnemonic application would then use an optical character reader (OCR) tool to convert the credit card image into numbers, which the mnemonic application would use to generate a mnemonic representation of the credit card number.

According to aspects of the invention, once the mnemonic application verifies the sensitive data, the algorithm of the mnemonic application is initiated to generate a mnemonic representation of the sensitive data using the encryption key, and the mnemonic is displayed to the user via the mobile device. In embodiments, the user then reads the mnemonic to the agent over the telephone connection and the agent enters the mnemonic into a mnemonic application on an agent-accessed server in order to decode the mnemonic back to the sensitive data, which the agent or a third party can utilize in a transaction (e.g., credit card purchase).

In aspects, a method is provided for sending confidential content, the method comprising: receiving on a mobile device an indication of a type of encryption; applying the type of encryption to a digital content that includes a confidential content; generating a mnemonic based, at least in part, on an encrypted version of the digital content; and sending, to a user of the mobile device, the mnemonic. In aspects, the method further comprises capturing an image of a written form of confidential content and generating the digital content based on a content of the image. In aspects, the receiving step of the invention includes receiving, on the mobile device, a salt for cryptography. In embodiments, the method includes sending, by the mobile device, the mnemonic to a computer device of a user that is permitted to view the confidential content. In embodiments, the method includes determining that a transaction has been initiated by the user.

In embodiments, the present invention provides a technical solution to the technical problem of securely communicating sensitive data telephonically between a caller and an agent, by providing a system that enables confidential communication of sensitive data over a telephone connection, such as in the instances where an exchange of digital data between the caller and the agent is impossible.

FIG. 2 shows an exemplary environment in accordance with aspects of the invention. The environment includes an agent server 50 (e.g., a web server) connected to a network 60. The agent server 60 may comprise a computer system 12 of FIG. 1, and may be connected to the network 60 via the network adapter 20 of FIG. 1. The agent server 50 may be configured as a special purpose computing device that is part of a payment processing system. For example, the agent server 50 may be configured to process credit card transactions. In embodiments, the agent server 50 includes a mnemonic application module 51 and an encryption key generator 52. In aspects, the agent server 50 is in communication with a telephone indicated at 53, which may be any type of conventional telephone device. The agent server 50 may be directly connected to the telephone 53, or may be connected through the network 60.

The network 60 may be any suitable communication network or combination of networks, such as a landline telephone network, a wireless telephone network, a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet). Also connected to the network 60 are user devices 70, 80.

Referring to FIG. 2, each user device 70, 80 may be a general purpose computing device, such as a desktop computer, laptop computer, tablet computer, smartphone, etc. In aspects, the user device 80 is in the form of a smartphone. In embodiments, the user device 70 may be in the form of a smart credit card. In embodiments, each user device 70, 80 includes a mnemonic application module (71, 81), a database (72, 82) and a data input device (73, 83). The data input device may be one or more input devices, such as a keyboard and a camera. In embodiments, the user device 70 may be a computing device separate from a telephone 74. The user device 70 may be in direct communication with the telephone 74 or the user device 70 may be in communication with the telephone 74 through the network 60. By way of example, the user device 70 may be a tablet in wireless communication with a mobile telephone 74 through a wireless network 60. In embodiments, the telephone 74 may not be in communication with the user device 70 at all, such as when a user is on a public pay phone and the user device 70 is a tablet computer. Further, although shown connected to the network 60, it should be understood that the user device 70 does not need to be connected to the network at all, in accordance with embodiments of the invention (e.g., such as when a network connection is not available to a user'). Further, in embodiments, a user device may include a text and or voice recognition module, shown as 85 in the user device 80.

Still referring to FIG. 2, the mnemonic application module 51 of the agent server 50 is configured to perform one or more of the functions described herein. The mnemonic application module 51 may include one or more program modules (e.g., program module 42 of FIG. 1) executed by the agent server 50. In embodiments, the mnemonic application module 51 is configured to decode a mnemonic received from a user. As used herein, the term mnemonic means a sequence of words that represents an encoding of sensitive data, such as a credit card number, a CCV number, a social security number, a password, etc. The mnemonic application module 51 may utilize mnemonic conversion algorithms to decode the mnemonic, as will be discussed in more detail below.

The encryption key generator 52 of the agent server 50 is configured to perform one or more functions described herein. The encryption key generator 52 may include one or more program modules (e.g., program module 42 of FIG. 1) executed by the agent server 50. In embodiments, the encryption key generator 52 is configured to generate an encryption key to be communicated to a user, such as through a telephone connection. In aspects, the encryption key is a short encryption key, such as a two character key.

Still referring to FIG. 2, the mnemonic application modules 71 and 81 of respective user devices 70 and 80 are configured to perform one or more functions described herein. The mnemonic application modules 71 and 81 may each include one or more program modules (e.g., program module 42 of FIG. 1) executed by the respective user devices 70, 80. In embodiments, the mnemonic application modules 71 and 81 are configured to generate a mnemonic of the secure data, as will be discussed in more detail below. The secure data, along with the mnemonic, may be stored in databases 72, 83 of the respective user devices 70, 80.

The text/voice recognition module 85 shown in FIG. 2 may be configured to perform one or more functions described herein.

In embodiments, the text/voice recognition module 85 is configured to recognize audio communications of encryption keys and convert the audio communications into text for storage in the user device 80. In embodiments, the text/voice recognition module 85 is configured to recognize text based information and transform the text based information into an audio communication of the information. Aspects of the text/voice recognition module 85 will be discussed in more detail below.

FIG. 3 shows a flowchart of a method in accordance with aspects of the invention. Steps of the method of FIG. 3 may be performed in the environment illustrated in FIG. 2, and are described with reference to elements shown in FIG. 2.

At step 300 a telephone connection is established between a user (using user device 80 or telephone 74) and an agent (using telephone 53). The telephone connection may be any type of conventional telephone connection.

Optionally, at step 301, user/device data or location data is sent to the agent. By way of example, global positioning system (GPS) location data from a user device 80 may be communicated to the agent server 50 by the user device 80. By way of another example, the user may verbally communicate location information to the agent. In aspects, the user device may convey user information, such as the language utilized by the user, to the agent.

At step 302, an encryption key is generated by an agent server 50. In aspects, the encryption key is generated by the encryption key generator 52 of the agent server 50. In embodiments, the encryption key is a short encryption key, such as a two character key. In aspects, the encryption key is selected based at least in part on user location data or user data. By way of example, if the user is an English speaker, the agent may utilize an encryption key associated with an indexed table of words in English in order to generate an English language mnemonic.

At step 303, the user receives the encryption key from the agent. This may occur in a number of ways. In embodiments, the encryption key is communicated directly from the agent server 50 to a user device (e.g., 70, 80) through the network 60. Such a communication may be in the form of a text message or email message, for example. In embodiments, the agent communicates the encryption key to the user verbally through the telephone connection.

At step 304, the user enters the encryption key into a mnemonic application module (71, 81) of the user device (70, 80). The user may enter the encryption key using the data input device (73, 83). The data input device (73, 83) may be a keypad, for example. Alternatively, in the case where an encryption key is sent directly to a user device (70, 80) through network 60, the mnemonic application module (71, 81) may obtain the encryption key directly from the encryption key communication. By way of example, the mnemonic application module 81 may recognize and import an encryption key received via text message from the agent server 50.

At step 305, the user enters sensitive data into the mnemonic application module (71, 81) using a data input device (73, 83) of the user device (70, 80). By way of example, a user can input the sensitive data via a keyboard, or via a camera of a user device (70, 80). In aspects, a camera is utilized to take a digital photograph of sensitive data, such as a credit card number, and the text/voice recognition module 85 is initiated to process the digital photograph and convert the digital representation of the sensitive data into text based data. Optical character recognition (OCR) techniques may be utilized by the text/voice recognition module 85. Alternatively, if sensitive data has already been stored in the user device (70, 80), such as during a previous mnemonic communicating event, the user may issue instructions to cause the mnemonic application module (71, 81) to receive or retrieve the sensitive data from a database (e.g., 72, 82) of the user device (70, 80).

Optionally, at step 306, the mnemonic application module (71, 81) stores the sensitive data (e.g., in database 72, 82). In aspects the sensitive data remains stored on the user device (70, 80) for use in future sensitive data communications.

Optionally, at step 307, the mnemonic application module (71, 81) verifies the sensitive data. By way of example, credit card number verification algorithms may be utilized to determine whether an entire credit card number has been received by the mnemonic application module (71, 81). In aspects, a check bit is utilized to determine whether an error has occurred in the transmission or storage of the secure data.

At step 308, the mnemonic application module is initiated by the user to generate a mnemonic for the sensitive data utilizing the encryption key. Mnemonic encoding algorithms may be utilized to produce a mnemonic in accordance with the present invention. By way of example, the mnemonic application module (71, 81) may include a table of words. The table of words may be indexed based on the encryption key. To encode a sensitive numeric sequence, such as a credit card number, the mnemonic application module (71, 81) calculates an integer quotient of the sequence divided by a count of the words in the table and calculates a remainder of the number divided by the count of the words in the table. The mnemonic application module (71, 81) selects the word in the table that is indexed by the remainder, and adds that word to the mnemonic. The mnemonic application module (71, 81) then calculates a new remainder of the integer quotient divided by the count of the words in the table and calculates a new integer quotient of the integer quotient divided by the count of the words in the table. This is repeated until the sequence of words in the mnemonic represents the encoding of the sensitive number sequence. In the case where the sensitive data is alphabetic, each letter of the alphabetic data can be first assigned a number, and the resulting number sequence may be utilized in the calculations described above. One of ordinary skill in the art would understand that numerous mnemonic generating techniques could be utilized in conjunction with the present invention, and the present invention is not intended to be limited to the example provided herein.

Still referencing FIG. 3, at step 309, the mnemonic generated at step 308 is displayed to the user through a display (e.g., smartphone display, monitor) of the user device (70, 80).

At step 310, the user communicates the mnemonic to the agent audibly over the telephone connection. By way of example, the user may verbally communicate the mnemonic to the agent through a telephone connection between the user telephone 74 and the agent telephone 53. Advantageously, any bystander witnessing the user's telephone communication would have no basis for decoding the mnemonic to obtain the original secure data. In embodiments, the text/voice recognition module 85 of the user device 80 may be utilized to recognize a text-based mnemonic generated by the mnemonic application module 81 and convert the text-based mnemonic into a synthetic voice output of the mnemonic to the agent. With this embodiment, any bystander witnessing to the user's telephone communication would be unlikely to hear the mnemonic, and would likewise have no basis for decoding the mnemonic to obtain the original secure data.

In step 311, the agent sends the mnemonic to the agent server 50. In aspects, the agent directly enters (via a keyboard or other input device) the mnemonic into the mnemonic application module 51 of the agent server 50. In aspects, the agent communicates the mnemonic to a third party agent, who then enters (via a keyboard or other input device) the mnemonic into the mnemonic application module 51 of the agent server 50. By way of example, a telephone agent using telephone 53 may communicate directly with a user through a user device 80, and may convey the mnemonic received from the user to a credit card processing provider managing the agent server 50.

In step 312, the mnemonic application module 51 of the agent server 50 decodes the mnemonic using the encryption key to obtain the secure data (e.g., credit card number). As noted previously, conventional mnemonic encoding systems may be utilized in this step of the present invention. By way of example, the mnemonic application module 51 of the agent server 50 may contain the same table of words as the mnemonic application module (71, 81) of the user's device (70, 80). By utilizing the encryption key (which is known to the agent) to index the table of words, the agent can decode the mnemonic utilizing the indexed table.

Optionally, at step 313, the mnemonic application module 51 on the agent server 50 may verify the sensitive data obtained at step 312. Verification algorithms can be utilized for this step. By way of example, a check bit may be utilized to determine whether an error has occurred in the transmission or storage of the secure data.

An exemplary use scenario will now be described with reference to FIG. 2. In this scenario, a user of a user device 80 (e.g., smartphone) is in a public location when the user finds it necessary to pay for a product or service over a telephone connection using a credit card number. The telephone agent receives user data from the user device 80 indicating that the user speaks English, and the agent server 50 generates an encryption key “pink bravo” (e.g., steps 301 and 302 of FIG. 3). The agent then verbally communicates the encryption key “pink bravo” over the agent's telephone 53 to the user via the user device 80 (e.g., step 303 of FIG. 3). The user hears the encryption key “pink bravo”, opens the mnemonic application module 81, and enters the key into the mnemonic application module 81 through a data input device 83 (e.g., keypad) of the user device 80 (e.g., steps 303 and 304 of FIG. 3). The user then enters a credit card number “0123 4567 8901 2345” into the mnemonic application module 81 through a touchscreen or keyboard of the user device 80 (e.g., step 305 of FIG. 3), and initiates the encoding function of the mnemonic application module 81 to generate a mnemonic representation of the credit card number “Blue Fox Sierra Mars Nevada” using the encryption key “pink bravo”, and display the mnemonic to the user through a display (e.g., 24) of the user device 80 (e.g., steps 308 and 309 of FIG. 3). The user then verbally communicates the mnemonic “Blue Fox Sierra Mars Nevada” to the agent over the telephone connection (e.g., step 310 of FIG. 3). The agent inputs the mnemonic “Blue Fox Sierra Mars Nevada” into the mnemonic application module 51 of the agent server 50 (e.g., step 311 of FIG. 3), and initiates a decoding process to transform the mnemonic back into the credit card number “0123 4567 8901 2345” using the encryption key “pink bravo” (e.g., step 312 of FIG. 3). The agent server 50 then runs a verification procedure to check for errors in the communication of the credit card number (e.g., step 313 of FIG. 3). Once verified, the credit card number is processed by the agent.
